SamSharp - Disable masking for possibly nicer voice

SamSharp came with a TODO at `Renderer.ProcessFrames.cs ln:167` that reads:
`// TODO: We should have a switch to disable this, it causes a pretty nice voice without the masking!`
Lets us do our due diligence and take up the torch. Would be nice to also submit this as a PR to the SamSharp repo.
